My dear Ravi,
Thanks for your cordial invitation. But I am unable to attend your birthday party. Dear friend, you know my half yearly examination is going on. There is a tough competition in my class. My rival no. 1 in this competition. Mr. Suresh is lagging behind me with a margin of two marks only. This time I am working very hard in my studies. I will surely leave him behind.
So, dear Ravi, believe me, I am really sorry. You the spirit of competition well. I hope you will excuse me.
I shall come when my examination will be over.
Wishing you many happy returns of the day.
Yours sincerely,
Samir.
